Question

Calculate the rotational inertia of a meter stick, with mass 0.50 kg, about an axis perpendicular to the stick and located at the 44 cm mark. (Treat the stick as a thin rod.)? ________ kg·m2

Answer 1

Length of meter stick

Mass of meter stick is located at center of meter stick at  

Distance between the center of meter stick and axis of rotation is

Moment of inertia of meter stick about an axis perpendicular to stick and passing through its center is

Using parallel axis theorem,

Moment of inertia of meter stick about the axis perpendicular to it and passing through 44 cm mark is
